Application filed October 14, sm. Serial No. 587,096.

.To all whom it may concern:

Be it known that I, Jam-1s 1V. Bananas,

v a citizen of the United t tates, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Cultivators. of which the following is a specification.

ll-iy mventio'n relates to the type of agricultural machines for cultivating growing.

crops known as eultivators, whether of the surface cultivating type, harr'ow, disk or auyother type. which operate to work the ground 'for the purpose of eradicating weeds andleaving the dirt in loosened .and.

1b softcondition, forming a mulch, around the stalks of the plants, and when desired to form the dirt in ridges aboutthe stalks.

.In order that a cultivator be adapted to A properly perform the cultivating operation, it is necessary that the devices which engage with the groundfor cultivating it be so supported that they .may be adjusted in a horizontal plane, and to varying inclined posi-- tions thereto in a vertical plane. In con- 4 structions, as commonly provided, certain adjustments of the cultivator-devices are provided for, butthese adjustments are of such a'character as notto provide adjustments'for all conditions of use; and furthermore, present objections which render uniform adjusting of all of the cultivatordevices a tedious operation.

My object, generally stated, is to provide improvements in cultivator-s to the end of rendering possible all of the required adjustments of the cultivator-devices and to permit such adjustments to be readily made. Referring to the accompanying drawings, Figure 1 shows by a view in elevation a common form of arch bar of a blade-cultivator equipped with crossheads andblades secured thereto in accordance with my invention; and Fig. 2, an enlarged perspective view of the connecting members between the arch-bar and the blades for providing adj ustments of the latter, these members being shown in disassembled but relative positions. As cultivators of the types to which my improvement relates are of well known 0 form, I have illustrated the archar only thereof, which is, as usual, supported on a wheel-supported frame (not shown) in such 3 a manner as to permit it with its titling at- E taehments to be swung from side to Jule in order to prevent the uproot-ing or cutting of the stalks of plants where the latter are out of line, the arch-bar in the operation of the cultivator straddling the plants as the cultivator is moved along the ground on its wheels. equipped at its lower ends with oppositely and outwardly extending members 4 bolted to the arch-bar, as represented at 5. Depending from each of the members 4 is a head 6 formed of two. members. 7 and 8.

The member 7 is'provided on its upper surface with a channel 9 adapted to receive an extension 10 on the member 4, which is slotted as represented at- '11 and through which slot-and an-opening 12 in thetad'acent member 7, a screw-bolt 13 extends,- or securing the member 7 to the part 4' in adjustable position thereon. The member 7 is formed with a depending flange 14 which serves as a point of attachment for the other companion member 8 of the head 6 .the member 8 being of angle construction a ording an u;)wardly-extending plate 15 andv a horizontallyextending plate 16. 'The plate 15 is pivoted to the flange 7, as by a bolt 17 passing through openings 18 and 19 in the parts 7 and 15 respectively, and to provide for the securing of the member 8 in any position of adjustment in the vertical plane liout its pivot 17, I employ a bolt 20 which extends through an opening 21 in the member 7, and an arc-shaped approximately vertically-exteiuling slot 22:. the member 15. Each of the plates 16 carries a bar 23, technically known as a crosshead, which extends transversely of the path in which the cultivator moves when in operation, these bars being pivoted to their supporting plates 16,

as through the medium of bolts 24 passing through openings 25 and 26 in the plates 16 and bars 23 respectively.. The bars 23 are adjustable on the plates 16 about their pivots 24, and to provide for the securing of the bars 23 in adjusted position, I provide bolts 2-? which pass through holes 28 in the ham 23 in elongated arc-shaped slots 29 in the coiiperating plates 16.

Each of the bars 23 terminates at its oppositc ends in split sleeves 30 provided with clamping devices 31, which may be of any suitable construction and secured within I'ln-sc l-;t(!\'S aredepending rods 32 to the lu\\' 'l ends of which. as shownin Fig. l,

liladvs 33 of the usual construction are secured. the split-sleeves at the ends of the The arch-bar illustrated at 3' isv bars permitting-the rods 32 to be secured therein in-anyposition of adjustment desired.

The members 7 carry forwardly-projecting extensions 34 which contain in their forward ends elongated arc-shapedeslots and openings 35: at which the draft-bars (not shown) usually provided in constructions of this character and connected with the tongue of the cultivator, are attached. Each plate 16 is provided with a rearward extension 36, apertured s represented at 37,

to. form a place of.ai ..chn ient for levelers which are commonly used in cultivators of this character.

It will be readily understood from the foregoing description that the adjustments provided between the members 8' and 7 and bar 2-3 permit the latter to be adjusted, as desired, in the horizontalplane and likewise in the vertical plane at the desired inclination to the horizontal, and that theseadjustments form between the bars 23'and the arch-bar, jointconnections whereby the blades 33 maybe adjusted to the desired inclination to the'horizontal plane, for varying the height to which the dirt is piled up around the stalks, and their inclination with relation to the line occupied by the plants, for varying-the amount of dirt displaced.-

It will also be noted that by providin independent adjustnfents in accordance-with the preferred embodiment of my invention, the

adjustment of the blades in both'the horizontal and vertical plane may be effected to a nicet-y, as the adjustment in each plane may be ctlected independently of the other. Furthermore where each bar 23 S11 ports twobla'des, the latter are caused to e adjusted simultaneously and thus the operation of setting the blades may be quicklyeffected.

It will be understood that while I have illustrated a cultivator in which blades form the cultivatingdevices, my invention is not limited in its use to such a type of cultivator as it may be readily embodied in other types thereof, as for instancein those in which instead of using blades as the cultivatingdevices, barrow-devices, disks or other suitable cultivating or -t1ll1ng devices which it is desirable be adjusted as described of the said arch-bar and adjustable thereon crosswi-se of the bar and formed with forwardly projecting extensions affording means at which the draft mechanism of the cultivator may be adjustabl secured, a cross-bar carrying the cultivating devices," and a head adjustably connecting said member and cross-- bar together in plane's extending at an angle to eac other, for the purpose set forth. 2. In a cultivator, the combination with -an arch-bar and a cross-bar carrying a culti vating dev1ce,'of means forad ustably conhecting said cross-bar. to said arch-bar comprising a member connected with an end of the arch-bar and adjustable crosswise there- 'ofand provided with a depending section and a forwardin .proj-ecting extension, which latter is a apted to be adjustably connected with the draft rig ing of the.cultivator,- and a head provide with substantiall vertical and-horizontalsurfaces, said hea l'fittin at its vertical surface against said depending section and at its horizontal surface against said cross-bar, a'ndi'meains,

for clamping said head to said depending section and cross-bar in adjusted positions with relation thereto, for the purpose set forth. I i JAMES W. BEGKMAN.
